V-类型球阀：用于不同应用的精确流控制

在工业阀领域中， V-型球阀在其独特的设计和出色的性能功能方面突出。该专业阀门由于能够处理具有挑战性的媒体并提供精确的流量调节，因此已成为各个行业的主食。

设计功能

顾名思义，v-型球阀的定义特征是球或座椅上的v形缺口。这种V形几何形状可以以不同的角度出现，例如15°，30⁰，45⁰，60⁰或90⁰。球通常是四分之一 - 球体，当阀体内旋转时，V -Notch与座椅相互作用以控制流动区域。阀体可以根据不锈钢，碳钢或其他合金等材料来构建，具体取决于应用要求。负责旋转球的茎可以由PEEK（聚醚 - 乙醚 - 酮）或金属制成，具有耐用性和对恶劣条件的阻力。

工作机制

V-型球阀的操作相对简单。可以使用手柄手动启动它，也可以使用执行器自动启动。打开阀时，球上的V -Notch的小端开始首先暴露流程路径。随着球的进一步旋转，流动区域随轴旋转以线性方式逐渐增加。该线性流量特性是一个重要的优势，因为它可以非常准确地控制流体流速。为了关闭阀门，球朝相反的方向旋转，最终将其紧密地密封在座椅上。手柄或执行器的四分之一转弯足以将阀门从完全开放到完全封闭的阀门，反之亦然。
